Abstract
A new genus of Chinese Delphacidae (Hemiptera: Fulgoromorpha), Hainanaella n. gen. with one new species, H. lutea n. sp. is described and illustrated. The new genus is assigned to the tribe Delphacini sensu Asche (1985, 1990), and subtribe Numatina based on the definition of Emeljanov (1993).
